To idle your vehicle with the automatic headlamp
system off, set the parking brake while the ignition is
off. Then start your vehicle. The automatic headlamp
system will stay off until you release the parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
Lamps On Reminder
A reminder tone will sound when your headlamps or
parking lamps are manually turned on, the driver's door
is open and your ignition is in OFF, LOCK or
ACCESSORY. To turn the tone off, turn the knob all the
way counterclockwise. In the automatic mode, the
headlamps turn off once the ignition key is in OFF.
Daytime Running Lamps
Daytime Running Lamps (DRL) can make it easier for
others to see the front of your vehicle during the day.
DRL can be helpful in many different driving
conditions, but they can be especially helpful in the
short periods after dawn and before sunset.The DRL system will make your headlamps come on at
reduced brightness when:
the ignition is on,
the headlamp switch is in automatic headlamp mode,
the light sensor detects daytime light,
the transmission is not in PARK (P), and
the parking brake is released.
When the DRL are on, only your headlamps will be on.
The taillamps, sidemarker and other lamps won't be on.
The instrument panel won't be lit up either.
When it begins to get dark, the headlamps will
automatically switch from DRL to the
regular headlamps.
The DRL system will turn off temporarily while the turn
signals are activated.
To idle your vehicle with the DRL off, put your
vehicle's transmission in PARK (P). The DRL will stay
off until you shift out of PARK (P).
As with any vehicle, you should turn on the regular
headlamp system when you need it.

2-36 Fog Lamps
Use your fog lamps for better vision in foggy or misty
conditions. Your low

your fog lamps to work.
The fog lamp switch is on the instrument panel under
the lamps switch. Press the switch to turn the fog lamps
on. Press the switch again to turn them off. A light will
glow in the switch when the fog lamps are on.
Fog lamps will go off whenever your high

headlamps come on. When the high beams go off, the
fog lamps will come on again.

make your instrument panel lights brighter. Turn the
thumbwheel all the way up to turn on the interior lamps.
Illuminated Entry
Your vehicle is equipped with an illuminated
entry feature.
When a door is opened, the dome lamps will come on if
the DOME OVERRIDE button is in the ªoutº position.
When all the doors are closed, or the front door handles
are lifted and released, the lamps will stay on for a short
period of time and will then turn off automatically. If
you use your keyless entry transmitter to unlock the
vehicle, the interior lights will come on for a short time
whether or not the DOME OVERRIDE button is in the
ªoutº position.
Exit Lighting
With exit lighting, the interior lamps will come on when
you remove the key from the ignition to help you see
while exiting the vehicle. With the DOME OVERRIDE
button in the ªoutº position, these lights will stay on for
a short period of time and then will go out.

Dome Lamps
The dome lamps will come on when you open a door.
You can also turn the dome lamps on by turning the

dome lamps will remain on until they are turned off.
You can use the DOME OVERRIDE button, located
below the parking/headlamp knob, to set the dome
lamps to come on automatically when a door is opened,
or to remain off. To turn the lamps off, press the button
into the ªinº position. With the button in this position,
the dome lamps will remain off when a door is open. To
return the lamps to automatic operation, press the button
again and return it to the ªoutº position. With the button
in this position, the dome lamps will come on when you
open a door. This will override the illuminated entry
feature unless you use your keyless entry transmitter to
unlock the vehicle.
Battery Run-Down Protection
This feature shuts off the dome, courtesy, vanity,
reading, glove box and underhood lamps if they are left
on for more than 20 minutes when the ignition is off.
This will keep your battery from running down.
If the battery run
-down protection shuts off the interior
lamps, it may be necessary to do one of the following to
return to normal operation:
Shut off all lamps and close all doors, or
turn the ignition key to RUN.

NOTICE:
Loading cargo that weighs more than 200 lbs.
(91 kg) on the luggage carrier may damage
your vehicle.
When you carry cargo on the luggage carrier of a
proper size and weight, put it on the slats, as far
forward as you can. Then slide the crossrail up
against the rear of the load, to help keep it from
moving. You can then tie it down.
Don't exceed the maximum vehicle capacity when
loading your vehicle. For more information on vehicle
capacity and loading, see ªLoading Your Vehicleº in
the Index.
To prevent damage or loss of cargo as you're driving,
check now and then to make sure the luggage carrier is
locked and cargo is still securely fastened.
Ashtrays and Cigarette Lighter
Pull the front ashtray door down to open it.
NOTICE:
Don't put papers and other things that burn into
your ashtray. If you do, cigarettes or other
smoking materials could set them on fire

To use the lighter, press it in all the way, and let go.
When it's ready, it will pop back by itself.
NOTICE:
Don't hold a cigarette lighter in with your hand
while it is heating. If you do, it won't be able to
back away from the heating element when it's
ready. That can make it overload, damaging the
lighter and the heating element.

While refueling, hang the cap by the tether from the
hook on the filler door.
To remove the cap, turn it slowly to the left
(counterclockwise). The cap has a spring in it; if you let
go of the cap too soon, it will spring back to the right.
CAUTION:
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline can spray out on you if you open the
fuel filler cap too quickly. This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any ªhissº noise to stop. Then unscrew
the cap all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See ªCleaning the
Outside of Your Vehicleº in the Index.
When you put the cap back on, turn it to the right
(clockwise) until you hear a clicking sound. Make sure
you fully install the cap. The diagnostic system can
determine if the fuel cap has been left off or improperly
installed. This would allow fuel to evaporate into the
atmosphere. See ªMalfunction Indicator Lampº in
the Index.

If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles (12 500 km) or 12 months
-- whichever
occurs first. Driving a vehicle with a fully warmed
engine under highway conditions causes engine oil to
break down slower.
Remote Oil Filter
The access door for the
remote oil filter is in the
steering linkage shield
assembly located under the
radiator support. Twist the
screw to unlock or lock
the door. If you open the
door, make sure it is
securely closed when you
are finished.
What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don't let used oil stay on your skin
for very long. Clean your skin and nails with soap and
water, or a good hand cleaner. Wash or properly throw
away clothing or rags containing used engine oil.
(See the manufacturer's warnings about the use and
disposal of oil products.)
Used oil can be a real threat to the environment. If you
change your own oil, be sure to drain all free
-flowing oil
from the filter before disposal. Don't ever dispose of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle it by taking it to a place that collects used oil.
If you have a problem properly disposing of your used
oil, ask your dealer, a service station or a local recycling
center for help.
